The brain is without a doubt the most complex organ in the human body, and that is why creating a synthetic natural brain is a very difficult task. But it appears like scientists are getting closer and closer to completing the task of making a machine that behaves like a natural brain. Scientists involved in the BrainScaleS project, a collaboration between 15 research institutions, are trying to create hardware which emulates parts of a natural brain.

Researchers at the National Institutes of Health have located a molecule in the brain that can be manipulated to either restore or erase memories, according to a paper published in the journal Science.
